It was announced on Tuesday morning (April 8) that Em and Rih Rih will be gracing the stage this Sunday during the annual event. This will be their first performance of "The Monster," the hit single from November's The Marshall Mathers LP 2. It reached #1 on the Billboard Hot 100.

The duo join previously announced performers twenty one pilots with their new single "Car Radio" and Ellie Goulding and Zedd, who will join forces to perform "Beating Heart" and "Find You."

Last week, Em released a behind-the-scenes clip of the song's music video. In it, the Rap God revisits scenes some of the music videos from earlier in his career, though he said that they didn't transport him to those days. "Redoing this scene actually brings back no memories for me because I don't remember it," he joked to the camera (with a straight face).

Another Slim video is on the way. Over the weekend, he posted an Instagram of him and Spike Lee, along with the caption, "Spike came out to The D for the 'Headlights' video...Coming soon."

The 2014 MTV Movie Awards will be hosted by Conan O'Brien. Make sure to tune in at 9 p.m. ET/PT this Sunday, April 13, when they air from Los Angeles' Nokia Theater.
